I must also say the conclusion of "What is Orientation in Thinking?" does remind a great deal of the conclusion of "What Is Enlightenment?"

Accept whatever seems most credible to you after careful and honest examination, whether it is a matter of facts or of rational arguments; but do not deny reason that prerogative which makes it the greatest good on earth, namely its right to be the ultimate touchstone of truth. If you fail in this respect, you will be unworthy of this freedom and will surely forfeit it; and you will bring the same misfortune down upon those other guiltless souls who would otherwise have been inclined to employ their freedom lawfully and hence in a manner conducive to the world's best interests!"

I have to say, he's pretty good when he's pissed off! :)
